Cardiac Calcified Amorphous Tumor in a Newborn

An ambiguous presentation of cardiac calcified amorphous tumor in a 37-year-old male

Calcified amorphous tumors are extremely rare benign cardiac lesions that can emerge in any chamber, and have many clinical obscurities. We herein report a case of a mid-aged previously healthy male with a complaint of recurrent chest pain. Echocardiogram revealed the presence of right atrial mass that was confirmed by transesophageal echocardiography. The patient underwent total resection of the mass with attached atrial wall. Pathological studies confirmed the diagnosis of calcified amorphous tumor. Five-year follow-up was uneventful with total symptomatic relief. In conclusion, we recommend considering the diagnosis of calcified amorphous tumors in any patient with intracardiac mass.

Cardiac Calcified Amorphous Tumor in the Neonatal Period

Calcified amorphous tumor (CAT) of the heart is a rare nonneoplastic cardiac mass that may exhibit symptoms resembling malignancy. In this report, we presented a 4-month-old male baby with repeated attacks of cyanosis and a cardiac murmur. Echocardiography revealed a tumoral noncircumscribed mass in the right atrium adhering to the interatrial septum which extends to the inferior vena cava. Cardiac exploration was carried out to excise the tumor. A histopathological study demonstrated the presence of thrombus-like tissue with extensive calcification and foreign body type giant cell reactions. After operation, the patient had an uneventful hospitalization. Although CAT is mainly diagnosed in adult patients, it should be considered in the causes of cardiac mass in the neonatal period.

The First Report of Calcified Amorphous Tumor Associated with Infective Endocarditis: A Case Report and Review of Literature

BACKGROUND Calcified amorphous tumor (CAT) of the heart is a rare non-neoplastic intracardiac mass, which is composed of calcium deposition surrounded by amorphous fibrous tissue. The clinical presentation of cardiac CAT resembles that of other cardiac tumors or vegetation, though there is no previous report of a CAT complicated with infective endocarditis. CASE REPORT A 67-year-old male with a history of end stage renal failure and gastric cancer who was on adjuvant chemotherapy presented with a cardiac mass. The mass was resected and diagnosed as CAT pathologically. Two separate sets of blood cultures were positive for Enterococcus faecalis, thus, the patient was diagnosed with infective endocarditis. Antibiotic treatment was continued for 6 weeks after surgery, and the patient recovered uneventfully. However, he died from a complication of his gastric cancer 5 months later. CONCLUSIONS This is the first report of CAT associated with infective endocarditis. Blood cultures should be obtained to differentiate infective endocarditis or CAT with infectious endocarditis from CAT alone, because CAT with infective endocarditis may present atypically and may be more likely to require antibiotic treatment along with surgery.

Multimodal imaging of cardiac-calcified amorphous tumor

Cardiac-calcified amorphous tumor (CAT) is a rare non-neoplastic tumor and its origin and pathogenesis are still unclear. In addition, it is difficult to clinically diagnose as cardiac CAT without pathological findings. We present a case of a 78-year-male diagnosed with cardiac CAT after surgical resection. We could evaluate tumor aspects by multimodal imaging including echocardiography, contrast-enhanced computed tomography (CT), magnetic resonance image, and 18F-fluorodeoxyglucose-positron emission tomography/CT before surgery.
